To all whom t may concern."

Be it known that I, WYNDHAM E. BAKKER,

I a citizen of the United States of America,

residing at. Fortuna, in the county of Humboldt and State of yCalifornia,have invented certain new and useful Improvements in` Rotary Sprinklers, of which the following is a specification. A

My present invention relates to improvements in rotary sprinklers, and is designed especially for the purpose of providing a long arm sprinkler adapted for use in gardens,

lawns, fields, etc., which is simple in construction and operation, comparatively cheap in first cost, durable, and eiicient.

The invention consists in certain novel combinations and arrangements of parts as hereinafter set forth and claimed.

In the accompanying drawings have illustrated one complete example ot the physical embodiment of my invention cony structed according to the best mode l have so far devised for the practical application of the princi les ofthe invention and this embodiment as proven highly satisfactory in actual practice.

Fi re 1 is a side' elevation of a rotaryl sprin er constructed and operating according to my invention.

Fig. 2 is a top plan view of the device of Fig. 1.

rig.

Fig. 3 is an enlarged, detail, sectional view of the fixed supporting head and water connections.

Fig. 4 is a top plan view of one of the nozles. v v

Fig. 5 is a sectional view on. line `5--5 Fig. e is a slightly mbdiea form of the invention. i

In the preferred embodiment of my inagainst the periphery of the pipe 3 and hold f it rigidly in' fixed position.

At its lower end below the head 2, the

fixed casing3 is externally threaded to receive the reducing socket 5, which has therein a rubber or leather gasket orwasher 6- provided .with an opening of less diameter than the bore of the connecting pipes, and a couplingy sleeve 7 is threaded into the rerrion duced end of the reducing socket. The hose coupling 8 is carried bythe sleeve, and if desired may be soldered to make a rigid fitting. The hose 9 is indicated as attached to thecoupling- -and through the hose the water, under pressure, flows to the sprinkling device. I

'The above described parts form the stationary support and connections for the' sprinkler which has a water pipe 10 with its exterior periphery turned smooth to fit neatly in the casing 3, and the water pipe is designed to revolvefreely and smoothly in the casing, which latter acts as a support and guide for the rotary or revolving parts,

Atits upper end the water pipeiis fitted and fixed the two-way casting 11, which has la bearing surface 12 on-the smooth top ledge of the xedcasing 3, and from this head the two sprinkler arms or pipe sections 13, 13 project diametrically, while the outer extensions or sections 14, 14 are threaded in the outer ends of the inner sections, and project therefrom as indicated.

Each sprinkler arm, at its backwardlyand upwardly turned ends, is provided with a closed cap 15 threaded on the arm, and provided with an opening 16 cut in the ed'ge. of

the cap/ and oblique to its longitudinal axis in'order to receive the inverted U-shaped,

l bent, copper plate 17 Awhich is soldered in the opening and fashioned with `a slit or slot- 18 to enable the cap to.y perform'the functions of a'nozzle and-spray a ifan-shaped emission yof water as the sprinkler arms re-4 volve. f Y

vLocated atright anglesto the sprinkler arms and extending diametricaliy are a pair of lateral brace arms 20, 20, threaded'into er arms and, brace arms as indicated, the tower consisting of a pipe threaded intothe top ofthe 'cast-I ing or head l1, but of course closed against ingress of water.

in Fig. 6 a slight modification is illus- ,the casting or sprinkler head 11, and wire".v Ibraces 21 extend from the to ofthe supporting tower l9 to the sprinll trated wherein the pi e A22 is fixed in the reducing socket 5, an a T-coupling 23 is threadedV on the lower end ofV this pipe and agpressure reducing plug 24 Ais adapted-to close the opening oi reduce the opening from the lateral enged sleeve 25 which is thread ed into the '-coupling and lies e hose Cou- @ling1 26 end hose 27 attached thereto.

The Water pressure is designed to be of s'uicient power to lift the revolving parts of the sprinkler from close rietional conv tact with the uppei edge of the outef easing and the Waslie 6, lout should the Wet-ei' pressure become of sufficient power to lift the i'evolving parts to such an extent that leaks slio'uld occur, the pressure muy be controlled by adjusting the plug 24 to Close the inlet oi' Water from inthe hose, or regulate it as desired.

@ne of the meritorious features of my invention fesides in the use of the longr spiinllei' arms by ineens et Wliieli a geat enea, may be spnilled er sprayed, and in seine instances when extremely long arms are used the'ti'ipod oi1 stand may be d1s pensed with and the revolving device be supported i-om a post oi' standard. lt willV be understood that di'erent lengths and sizes of pipes and fittings may be used, and the embodiment of my invention may be alteied oi changed Within the scope of my claim Without departing from the spirit of my intention.
